Transfection of neurons can be achieved in a rapid and stable way by using polyethyleneimine (PEI) as a DNA vector. Foreign genetic material has been introduced into postmitotic rat sympathetic neurons and human retinal neurons.

In SOD1-G93A mouse models of amyotrophic lateral sclerosis, a ketogenic diet may prolong motor function through increased ATP production and protection of motor neurons from certain mitochondrial toxins.

Neurons originating in the prefrontal cortex transmit information about the environment relatively directly to the spinal cord, enabling organs to respond appropriately. There is just one structure in the middle - the hypothalamus.

Wallerian degeneration progresses rapidly along wild-type axons, whereas nerves from the WldS mutant mouse degenerate by a fundamentally different mechanism, with a slow anterograde decay as axonal components are gradually depleted.

Images can be perceived more quickly when accompanied by sound as indicated by the improved response time of monkey visual neurons, which are able to integrate signals from the auditory cortex without involving other brain areas.

Reduction of hypothalamic agouti-related peptide expression in mice by RNA interference is associated with an increase in metabolic rate and a reduction in body weight without any change in food intake.
